Point-Free is a video series exploring advanced topics in the Swift programming language, hosted by industry experts, Brandon and Stephen.
We continue our series on “modern persistence” with an important topic: “callbacks.” Callbacks are little hooks into the lifecycle of your data model so that you can be notified or take action when something changes. We will first explore the “Active Record” pattern of callbacks, popularized by Ruby on Rails, and then see how we can improve upon them.
How does our SQL-based solution for persistence compare with modern SwiftData? We put things to the test by rebuilding our complex @FetchAll
query using @Model
and the @Query
macro!
We finish a sneak peek of our upcoming Structured Queries library by showing how queries built with the library can be reused and composed together, and how we can replace all of the raw queries in our application with simpler, safer query builders.
We build a bunch of triggers in a schema-safe, type-safe way using APIs from the StructuredQueries library, including a callback that ensures the Reminders app always has at least one list, and a callback that helps us support drag–drop positional ordering of lists.

We go live with our viewers to unveil our vision for modern persistence. We show just how easy it is to seamlessly synchronize your app’s data across many devices, including sharing data with other iCloud users, and we answer your questions.
We dissect some of the most important and interesting topics in Swift programming frequently, and deliver them straight to your inbox.
We cover both abstract ideas and practical concepts you can start using in your code base immediately.
Download a fully-functioning Swift playground from the episode so you can experiment with the concepts discussed.

Architecture is a tough problem and there’s no shortage of articles, videos and open source projects attempting to solve the problem once and for all. In this collection we systematically develop an architecture from first principles, with an eye on building something that is composable, modular, testable, and more.
SwiftUI is Apple’s declarative successor to UIKit and AppKit, and provides a wonderful set of tools for building applications quickly and effectively. It also provides a wonderful opportunity to explore problems around architecture and composition.
What are the best, modern practices for persisting your application’s state? We explore the topic by rebuilding Apple’s Reminders app from scratch using SQLite, the most widely deployed database in all software. We will dive into many of SQL’s most powerful features, such as foreign keys, triggers, common table expressions, and more.
If you have ever created a binding using the get:set:
initializer, you may want to reconsider. Doing so can hurt SwiftUI’s ability to animate your view. Luckily there is a better way. You can leverage @dynamicMemberLookup
and subscripts to derive new bindings in a way that allows SwiftUI to propertly track where the binding came from.
SwiftData is not capable of filtering and sorting by raw representable enum properties in models. Predicates and sort descriptors will compile just fine when referencing enum properties, but it will crash at runtime.
SwiftData is not capable of sorting by boolean properties in models. And if you try to trick SwiftData to allow it, you will encounter runtime crashes.
The best thing, that happened to me for a while. @mbrandonw and @stephencelis really provide a lot of new information according to #ios development and #functionalprogramming. All info could be used in real production without boring academics.
So many concepts presented at #WWDC19 reminded me of @pointfreeco video series. 👏👏 So happy I watched it before coming to San Jose.
Every episode has been amazing on Pointfree, yet somehow, you've managed to make these Parser combinator episodes even better!!! ⭐️⭐️⭐️⭐️⭐️
I listened to the first two episodes of @pointfreeco this weekend and it was the best presentation of FP fundamentals I've seen. Very thoughtful layout and progression of the material and motivations behind each introduced concept. Looking forward to watching the rest!
Three recent @pointfreeco episodes were so interesting I stayed in the treadmill 3x as long as usual and watched them all in a row! Walking may be challenging later/tomorrow... 😮
I bought the annual subscription and after I watched all videos and played with the sample code and libraries I can say it was the best money I spent in the last 12 months.
Just became a subscriber! I'm binge watching episodes now! Great content! I'm learning so much from you guys. The repo for the site is the best go-to reference for a well done project and swift-web is something I am definitely going to use in my projects. Thanks for everything!
Thanks @mbrandonw @stephencelis for the very pedagogical series with @pointfreeco Excited and looking forward to learn from the series
@pointfreeco ❤️: Thank you! 🧠: … The brain can’t say anything. It is blown away (🤯)!
